The CDC2 (Phospho-Tyr15) Colorimetric Cell-Based ELISA Kit is a convenient, lysate-free, high throughput and sensitive assay kit that can detect CDC2 protein phosphorylation and expression profile in cells. The kit can be used for measuring the relative amounts of phosphorylated CDC2 in cultured cells as well as screening for the effects that various treatments, inhibitors (ie. siRNA or chemicals), or activators have on CDC2 phosphorylation.
Qualitative determination of CDC2 (Phospho-Tyr15) concentration is achieved by an indirect ELISA format. In essence, CDC2 (Phospho-Tyr15) is captured by CDC2 (Phospho-Tyr15)-specific primary antibodies while the HRP-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the HRP enzyme conjugated to the secondary antibody can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of the Cell-Based ELISA, multiple normalization methods are needed:
| 1. | A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target absorbance values. |
| 2. | Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method may be used to determine cell density. After staining, the results can be analysed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted. |

| UniProt Protein Function: | CDK1: a protein kinase of the CDK family. Catalytic subunit of the conserved protein complex known as M-phase promoting factor (MPF), which is essential for G1/S and G2/M phase transitions. Mitotic cyclins stably associate with this protein and function as regulatory subunits. Its activity is controlled by cyclin availability and phosphorylation through the cell cycle. Activated in many cancers including colon, liver and breast. The T isoform, which lacks a regulatory region, is expressed in breast cancer. Inhibition in cancer cells may drive cells into apoptosis. May also drive cell migration. Inhibitors: BMS-265246, BMS-265246-01. 2 isoforms of the human protein are produced by alternative splicing. |

| NCBI Summary: | The protein encoded by this gene is a member of the Ser/Thr protein kinase family. This protein is a catalytic subunit of the highly conserved protein kinase complex known as M-phase promoting factor (MPF), which is essential for G1/S and G2/M phase transitions of eukaryotic cell cycle. Mitotic cyclins stably associate with this protein and function as regulatory subunits. The kinase activity of this protein is controlled by cyclin accumulation and destruction through the cell cycle. The phosphorylation and dephosphorylation of this protein also play important regulatory roles in cell cycle control. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009] |
